Silca TPU Tube

The Silca TPU Tube is an advanced inner tube crafted from thermoplastic polyurethane, combining exceptional weight savings, compactness, and durability. Engineered for riders who demand performance without compromise, this tube delivers near-latex rolling characteristics while offering greater ease of handling and reliability in the field.

Thanks to its patented mechanical valve attachment, this tube resists valve pull-out and maintains a secure connection under high inflation pressures. Its durable welded construction and aluminum valve design make it rugged enough to handle modern pump technology and long service life in demanding environments.
